Generate High-Quality PDF

The steep, glaciated Chelan Tephra Hills ecoregion is dominated by deep deposits of coarse, volcanic ejecta which contribute to the character of this dry, east-side region. Elevations range from 1200 to 5700 feet. Ponderosa pine grows in lower areas, Douglas-fir occurs in the mid-elevations, and subalpine fir is found above 5000 feet in elevation.
